Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) = - x² - 1
- g(x) = x + 5
<u>Find f(g(x)):</u>
- f(g(x)) =
- f(x + 5) =
- - (x + 5)² - 1 =
- - x² - 10x - 25 - 1 =
- - x² - 10x - 26

2x+x+x+15=47
4x+15=47
4x=32
x=8
2x=16
x+15=23
Answer:x=2
y=6
Step-by-step explanation:
-7*x+4*y=10
║minus
-5*x+3*y=8
----------------
-2*x+y=2
y=2+2*x
-------------
-5*x+3*(2+2*x)=8
-5*x+6+6x=8
x=8-6
x=2
-------------------------
-7*2+4*y=10
4*y=10+14
4*y=24
y=24/4
y=6
Answer:
slope if -7/8 and y-intercept is 43/16
Step-by-step explanation:
-5+14x+16y=38
14x+16y=43
16y=43-14x
16y=-14x+43
y=-7/8x+43/16
Therefore, slope if -7/8 and y-intercept is 43/16
